Struct SceneReturnReceiver

pub struct SceneReturnReceiver<S> { /* private fields */ }

Expand description

The UI-thread handle to scene_return_channel: polls (never blocks) for a scene the render thread has finished with.

Implementations§

impl<S> SceneReturnReceiver<S>

pub fn try_recv(&self) -> Option<S>

Non-blocking poll for a returned scene — None if the render thread hasn’t given one back yet (cold start, or it is still busy on the current frame). Never blocks: a caller that finds nothing falls back to allocating a fresh scene (Scene::new()).
